Top 10 Flat, Black Rash Causes

  1. 1.Non - Specific Skin Rash

    A rash is an area of irritated or swollen skin. Often, rashes are unidentifiable and some variation of normal. For example, scratching one's arm causes it to turn red (which is caused by mast cells releasing chemicals into the local area), but that's completely normal.

    At this time, you do not need treatment for this rash. If it worsens, you may need to consult a physician.

  2. 2.Normal Case of Vaginal Discharge

    Vaginal discharge is a common issue many women experience and is likely nothing to worry about. Your vaginal discharge can change depending on your menstrual cycle. Recent initiation or a change in contraceptives can also cause a temporary change in discharge.

    You most likely have nothing to worry about. If the discharge becomes severe or you have other symptoms like itching or foul odor, you should speak with your primary care physician or OBGYN.

  4. 4.Normal Case of Spotting

    Spotting is vaginal bleeding that occurs between periods. Many women experience spotting between periods and it is often nothing to worry about. Oral contraceptives (the pill) can cause spotting as a side effect, especially if they have a low estrogen dose, someone started on them recently or does not take them on the same time everyday. Additionally, hormone supplements that only contain estrogen (often used in menopause) can cause spotting as well.

    You most likely have nothing to worry about. If you take the pill, try to take it at the same time every day. If the spotting becomes severe or is bothersome, you should speak with your primary care physician or OBGYN.

    Common

    vaginal bleeding or bloody discharge, bloody vaginal discharge, mild unexpected vaginal bleeding, vaginal bleeding, vaginal discharge

  5. 5.Pelvic Inflammatory Disease

    Pelvic inflammatory disease (PID) is an infection of the female genital structures like the uterus, fallopian tube, ovary, and the surrounding abdominal wall. It is typically caused by N. Gonorrhoeae or C. Trachomatis.

    You should contact your doctor today. There, physical exams and swabs of the vagina will be needed to look for infection. Further blood testing or imaging may also be needed. Treatment involves antibiotics (orally) for both you and your partner

    Eczema is a form of skin inflammation that causes skin to be dry, itchy, red, and irritated.

    You should go to your local pharmacy or retail clinic to be treated. The usual treatment for atopic eczema involves avoiding irritants and other triggers, using moisturizers to prevent inflammation, as well as steroid creams and ointments when the inflammation flares up.

  10. 10.Strep Throat Requiring Throat Swab

    Strep throat is a bacterial throat infection that can make the throat feel sore and scratchy. Only a small portion of sore throats are the result of strep throat. And, if you do not show enough signs of a true strep throat, testing may be needed before treatment is begun.

    You should visit your primary care physician within the next 24 hours, where a diagnosis can be made via a "rapid antigen test" (it's a throat swab). Treatment with simple antibiotics would be given only if the test is positive. It is important to get treatment, however, because of the possibility of getting a disease called "rheumatic fever" after the strep throat infection.

    Rarity:
    Common
    Top Symptoms:
    fatigue, nausea, sore throat, fever, rash
    Symptoms that always occur with strep throat requiring throat swab:
